|Oracle® Fusion Middleware Developer's Guide for Content Server
11g Release 1 (11.1.1)
Part Number E10807-01
In previous versions of Content Server, when a component writer wanted to create an HTML table like those used on the search results page, HTML code had to be copied and pasted. The information in the tables was mixed with the HTML, with no separation between data and display.
The same issue was true for action menus. Data and display for the tables and menus were tightly coupled, making it impossible to perform global changes to all tables in the Content Server except for those changes done with CSS modifications. It was also difficult for components to target and modify specific aspects of both the tables and the menus.�
To customize a page's action menu, a developer can override one of the following include files then modify the PageMenusData resultset. These includes are all defined in the DomainHome/resources/core/resources/std_page.idoc file:
In addition, tables like the one used on the search results page can be created by setting up result sets of data then calling specific resource includes which use that data to display the page. Result sets can also be used to create action menus like those found on the Workflow In Queue and Search Results pages.
The action menu and HTML table display frameworks allow developers to create quick and flexible Web pages that match the look and feel of the rest of the system. They also allow component writers to easily extend, add to, and override any or all of the Headline View, or Thumbnail View tables on the server, and any of the action menus.�
Different display tables are used for the search results page for each display type (Headline, or Thumbnail) with an API for each. Each type is discussed in the follow sections:
One of the first steps in any table setup is to retrieve documents to display, as in this example:�
<$QueryText = "dDocAuthor <matches> `sysadmin`"$>� <$executeService("GET_SEARCH_RESULTS")$>�
The following example shows how to create a Headline View table. The concepts discussed here are also used to create the other table types.
The initial step in this process is to create a result set that describes the columns of the table, as in this example:�
<$exec rsCreateResultSet("ColumnProperties", "id,width,headerLabel,rowAlign")$> <$exec rsAppendNewRow("ColumnProperties")$> <$ColumnProperties.id = "dDocName"$> <$ColumnProperties.width = "150px"$> <$ColumnProperties.headerLabel = lc("wwDocNameTag")$> <$ColumnProperties.rowAlign = "center"$> <$exec rsAppendNewRow("ColumnProperties")$> <$ColumnProperties.id = "dDocTitle"$> <$ColumnProperties.width = "auto"$> <$ColumnProperties.headerLabel = lc("wwTitle")$> <$ColumnProperties.rowAlign = "left"$> <$exec rsAppendNewRow("ColumnProperties")$> <$ColumnProperties.id = "actions"$> <$ColumnProperties.width = "75px"$> <$ColumnProperties.headerLabel = lc("wwActions")$> <$ColumnProperties.rowAlign = "center"$>�
A result set called
ColumnProperties is created. Each row in the table corresponds to a column on the table to be created. Each column can have several attributes associated with it. Some of the more common attributes are:�
id: This is a mandatory attribute. Each column in the table being created must have an ID associated with it. The ID is used later to determine what will be displayed in every row.�
width: The width of the column. This can be any CSS width declaration such as
auto, which causes the column to auto-size, filling as much of the table as possible.�
headerLabel: The text to be displayed in the header of this column.�
rowAlign: An indication of whether the contents should be left, right, or center aligned.
headerURL: Used to link the column header text to a URL�.
The next step is to determine what data will be displayed in each row of the table.�
<$exec rsCreateResultSet("RowData","dDocName,dDocTitle,actions")$> <$exec rsAppendNewRow("RowData")$> <$RowData.dDocName = "<$dDocName$>"$> <$RowData.dDocTitle = "<$dDocTitle$>"$> <$RowData.actions = "<$include doc_info_action_image$>"$>
The ColumnProperties result set technically has a row for each column in the table, while in RowData, there is only one row. Data entered into this result set is of the following form:�
<$RowData.%COLUMN_ID% = "%IDOCSCRIPT%"$>�
Each column in the
RowData result set refers to an actual column that will appear in the final table. Each column in this result set has a corresponding "ID" in the
ColumnProperties result set declared earlier. An IdocScript expression is assigned to each cell in this result set. It will then be evaluated during the display of each row as it is written to the HTML document.
Next the resource include must be created to display each row in the table.�
Calling this resource include creates the
slim_table_row_include resource include. Instead of parsing and evaluating the
RowData result set for each row in the table, it is done once.
Use the following steps to set multiple row includes (for example, for a single table which displays different rows for different types of items):
Delete and re-create the
RowData result set.
rowIncludeName to the name of the resource include to create.
The following code displays the table:�
<$include slim_table_header$> <$loop SearchResults$> <$include slim_table_row_include$> <$endloop$> <$include slim_table_footer$>�
To make the table look like the table on the search results page, set the following in the script:
<$UseRowHighlighting = true$>�
One special customization with the Headline View table allows any component writer or administrator to easily override how the data in any column is presented. For example, a custom include similar to the following can be declared from in a component:
<@dynamichtml slim_table_title@> <b><$dDocTitle$></b> <@end@>
dDocTitle:slimTableCellInclude=slim_table_title is added to the IntradocDir/config/config.cfg file or set from within a script, all Headline View tables with a column ID of dDocTitle are displayed using the defined custom include.� This overrides the
RowData for these columns.�
The table for the Thumbnail View is created differently. The
RowData result sets are not constructed. Instead, the number of columns are set and an IdocScript include name is used to "paint" each cell. This is less easy to customize and less data-driven than the other methods, but this type of table is also much less structured.�
<$numDamColumns = 4$> <$damCellIncludeName = "my_sample_dam_cell"$> <$include dam_table_header$> <$loop SearchResults$> <$include dam_table_item$> <$endloop$> <$include dam_table_footer$>
The first step in customization is to add the action menu icon to the actions column.� The following example incorporates an action menu into each row of the Headline View sample table used previously.
<$RowData.actions = "<$include action_popup_image$>" & " <$include doc_info_action_image$>"$>
This inserts the action image into the appropriate column. However, clicking it does nothing because the actual menu is not written to the HTML page.
The following code creates the data to be used to construct this menu:�
This code creates a result set called
PopupProps, where each row corresponds to an action in the menu being created. Each action can have several attributes associated with it. Some of the more common attributes are:�
label: A string displayed as the label for the action.�
class: A classification for this action. It can be something as simple as "search", "document", "workflow", or even the name of your component. It places the action into a group so it can be quickly enabled or disabled with the rest of the actions within that same group.�
id: Another method of classification, much more specific than "class". This method should be unique to the application, and you can use it to hide certain actions from appearing within the menus.
ifClause: An optional attribute evaluated every time that action is about to be written to the HTML document. If the clause evaluates to FALSE, the action is not displayed.
isDisabled: If set to 1, the action is never displayed.
linkTarget: Used to make this link open a page in a different window. This attribute points to any anchor tag target.�
After the data is set, it can be used to create an IdocScript resource that writes this action menu.�
This resource works like
create_slim_table_row_include. It constructs a new IdocScript resource called
action_popup_container_include. To rename it, set set
<$actionPopupContainerIncludeName = new_include_name$> in the script.
Use the following code to have this include called for each row of the Headline View table.�
<$exec rsCreateResultSet("PopupData", "actions")$> <$exec rsAppendNewRow("PopupData")$> <$PopupData.actions="<$include action_popup_container_include$>"$>
�This code creates a
PopupData result set similar to the
RowData result set. It is structured in the same way, and is used as a location to print the action menu containers which are hidden until a user clicks on the action image.
The table created now has action menus, similar to those normally seen on the search results page whenever the appropriate image is clicked.�
Editing these actions is done by adding and deleting rows from the
PopupProps result set or editing rows that already exist. In addition to this type of customization, actions can be hidden by setting the
disabledActionPopupIds variables. These can be set in the config/config.cfg file or in the Idoc Script itself. For example:�
<$disabledActionPopupClasses = "workflow,folders"$> <$disabledActionPopupIds = "getNativeFile,alertDocName"$>
Setting these variables causes any actions whose class is either
folders, or whose ID is
alertDocName, to always be hidden. Using these variables enable Content Server administrators and component writers to hide specific actions either globally or for specific pages.�
�Component writers also can override a number of Idoc Script resource includes to modify functionality in this area on either a global or targeted scale. The following includes are just a few of the available resource includes:
